i think i am getting to much pressure to the turbo, and it goes past the oil seals, which is why i have small amounts of oil in both ends, only the compresor for sure though, not alot, just a tad, so thats my assumption.
i plan to get a rebuilt kit, rebuild the turbo, then have it balanced and put it back on with an oil restrictor.
is there a possibility my ebay exhaust housing is warped or something where the CHRA meets the housing, an is not sealing all theway? is super tight
You guys have to be doing something wrong because what makes my applications any different from most of yours, yet you guys' turbos are all taking on oil. Let me make this perfectly clear, neither your manifold or your exhaust components are causing your problems . Now that we've gotten that cleared up, let's try and make some sense of your claims. High oil pressure: Oil pressure is high on a cold engine for obvious reasons. That pump has to make sure there's enough pressure and volume to get oil from your sump to your head in the shortest amount of time. The natural characteristics of a good CA18 oil pump will show at least 50-75psi of cold engine oil pressure upon idle and 100+if you're revving the thing; this is normal. If you go revving on it while the pressure is that high, then you're an "Idiot"that like spending money.
I have a brand new turbonetics turbocharger on my CA powered 240sx as well and I too have high oil pressure in the A.M. I also rev my engine (I'm an IDIOT) when it's cold because of the massive injectors I'm using, but I don't have the issues you guys are all claiming you have. Hell, my turbonetics turbocharger doesn't even have the restrictor that everyone says you should have, but again, it's not spewing oil all over the place. To make matters worse, I 2-step my engine at or around 6500rpm, but still no smoking from oil issues.
I also have 2 sentras both with GT35R ballbearing units, again, no oiling issues and they both have massive injectors as well as high cold engine oil pressure, so some revving is needed. So in theory consider this: you guys could just possibly have bad turbochargers?
And some of you claim you need to prime the engine to prime the turbo before actually running the engine? In my experience and per my turbo vendor, this is not necessarily true. These turbochargers or most anyway are pre-lubed and can be activated without massive amounts of oil for a few seconds, seeing that the exhaust temperatures are not that severe during start-up. A poorly built unit will fail almost immediately whereas a well-built unit should not face failure when it gets a little oil when it needs oil to survive anyways. Hope this helps a bit and if not, good luck with your issues because there is no way that high oil pressure is causing failure when your cartridge is a flow-through system. Unless your return line is kinked, rule-out high oil pressure and consider the fact that you just got a bad unit.
